Conor McGregor compared himself to Elon Musk during fiery exchange with a key member of Floyd Mayweather's team

Conor McGregor has told Floyd Mayweather's right-hand man that he should call him Elon Musk.

McGregor had been critical of the $9 million Mayweather collected for obliterating 20-year-old Japanese fighter Tenshin Nasukawa inside one round on New Year's Eve.

Leonard Ellerbe, the CEO of Mayweather Promotions, clapped back, saying McGregor does not want "that smoke" again — a clear reference to Mayweather's victory over McGregor in 2017.

McGregor attempted to end the war of words by claiming it is he who is armed with a flamethrower, and that Ellerbe should just call him Elon.

Conor McGregor just compared himself to Elon Musk during a fiery exchange with a key member of Floyd Mayweather's entourage.

The UFC fighter reignited his social-media crusade against Mayweather after the retired American boxer announced a three-round exhibition against the 20-year-old Japanese kickboxer Tenshin Nasukawa at the Rizin 14 show in Japan on December 31.

Last year, McGregor downplayed the bout as "something out of Rush Hour 5."

During an expletive-laden Instagram rant in November, McGregor said: "What in the f--- is going on here? Chris Tucker and Jackie f------ Chan back in this b----. F------ brilliant. Mad little b------ you are Floyd. Fair f---- to you mate. No lie. F--- it."

First, McGregor scoffed at the reported $9 million Mayweather banked for participating in the Saitama show. He said: "That 9 milli won't keep you on top of my list for long, kid," — a clear reference to Forbes' richest athlete list, which is a ranking Mayweather dominated in 2018, and one McGregor hopes to top in the years ahead.

Just ten minutes after McGregor published his social-media post, the CEO of Mayweather Promotions Leonard Ellerbe slapped the Irishman with a reminder that he lost 2017's crossover bout between the two fighters.

"Champ, champ with all due respect I don't think you want that smoke again," Ellerbe tweeted on Tuesday.

Not to be outdone, McGregor quickly replied by claiming he is the one armed with a flamethrower, and that they should call him Elon Musk.
